Recently, as two heavy-duty trucks carrying polymerization reactors slowly drove out of Nanjing Tianhua Chemical Engineering Co.
, Ltd.
, a subsidiary of Tianhua Institute, the CNOOC Ningbo Daxie Petrochemical Rum designed and manufactured by Tianhua Institute The first domestically produced polypropylene (PP) polymerization reactor of Sri Lanka Process was successfully delivered
.
The Lums process is a gas phase polypropylene process
.
Because it can flexibly arrange the layout of the reactor, two reactors can be connected in series or in parallel according to the needs, and a variety of polypropylene products can be produced at the same time
CNOOC Daxie Petrochemical experts considered that the comprehensive strength of CNOOC Daxie Petrochemical Co.
, Ltd.
could meet all the requirements of polymerization reactor design and manufacturing, and finally determined that Tianhua Institute would undertake the localization of the polymerization reactor of CNOOC’s 300,000-ton/year polypropylene project.
Design and manufacturing tasks
.
In order to ensure the successful completion of the project, Tianhua Institute set up a project team, combined with the use of CNOOC Daxie petrochemical equipment, formulated a detailed design plan, and put forward higher design and manufacturing requirements for the key processing parts of the reactor
.
They focused on the difficulties in the design and manufacture of the polymerization reactor, innovatively adopted 3D laser scanning technology, and controlled the accuracy of the reactor butterfly head at 0.
He Deqiang, deputy general manager of Tianhua Institute and general manager of Nanjing Tianhua, said that the implementation of the project has filled the gap in the domestic design and manufacture of polypropylene reaction equipment, and has also improved the comprehensive capabilities of Tianhua Institute for research, design and manufacturing and the core competitiveness of the enterprise.
